Disposable anesthesia face mask

ABSTRACT

A disposable anesthesia face mask comprising a shell member having an annular flange and a do-nut shaped pneumatic sealing cushion attached to the shell member annular flange. The shell member and its flange are pear-shaped defining a nasal portion of first transverse extent, a mouth portion of second transverse extent, and an under-the-chin engagement portion of third transverse extent where the second transverse extent is greater than the first transverse extent and the third transverse extent is greater than the second transverse extent.

FIG. 1 is a front elevational view of the disposable anesthesia face mask showing my new design;

FIG. 2 is a rear elevational view thereof;

FIG. 3 is a top plan view thereof;

FIG. 4 is a bottom plan view thereof;

FIG. 5 is a right side elevational view thereof;

FIG. 6 is a left side elevational view thereof; and,

FIG. 7 is a right side elevational view thereof showing my new design in use position.

The even broken line immediately adjacent to the claimed design represents the bounds of the claimed design. The dash-dot-dash line represents a human form in FIG. 7 which forms no part of the claimed invention. The dash-dot-dash line showing a portion of the cushion is included for the purpose of illustrating environmental structure and forms no part of the claimed design. None of the broken lines form any part of the claimed design. 

The ornamental design for a disposable anesthesia face mask, as shown and described.
